Abstract

The invention relates to manoeuvring members for doors particularly adapted for doors with an anti-panic bar that can be subject to hooliganism by a sustained pressure on the lever handle. The invention provides a manoeuvring member of the semi-assembly type that is not damaged by an excessive effort on the lever handle. To this end, the invention provides a manoeuvring member including: a lever-handle holder with an abutment part; a follower; a control cylinder; a mobile assembly for a mobile translation transmission along a translation direction parallel to the reference plane, that can be switched at least between an engaged configuration and a disengaged configuration; an abutment system adapted, in a first configuration, to interact with said abutment portion for defining an abutment angular position for the lever handle holder, said abutment system being deformed by increasing forces applied on the lever handle holder until it reaches a second configuration in which the abutment portion is disengaged from said abutment system by sliding when contact the same, said abutment system being elastically brought back to its first configuration.

Description

L'invention concerne un organe de manoeuvre pour porte, en particulier adapté aux portes munies d'un barreur anti-panique.The invention relates to a door operating member, in particular adapted to doors provided with an anti-panic helmsman.

En pratique, le barreur anti-panique d'une telle porte se trouve du côté intérieur de la porte pour permettre l'évacuation rapide d'un local, et l'organe de manoeuvre (ou demi-ensemble) a pour fonction de contrôler l'accès au local depuis l'extérieur de la porte. Un tel demi-ensemble est généralement muni d'une béquille et d'un cylindre de commande, l'action au cylindre permettant d'autoriser l'ouverture de la porte par action sur la béquille, ou au contraire d'interdire celle-ci. L'ouverture de la porte se fait en pratique par action sur un fouillot entrainant le carré de la serrure.In practice, the anti-panic helper of such a door is on the inside of the door to allow rapid evacuation of a room, and the operating member (or half-assembly) has the function of controlling the access to the premises from outside the door. Such a half-assembly is generally provided with a crutch and a control cylinder, the cylinder action to allow the opening of the door by action on the stand, or on the contrary to prohibit it . The opening of the door is done in practice by action on a follower driving the square of the lock.

On connaît des dispositifs à béquille bloquée : lorsque l'accès depuis l'extérieur est condamné, la béquille est bloquée en position d'attente, généralement horizontale.Standstand devices are known: when access from outside is condemned, the stand is locked in the waiting position, generally horizontal.

On connait aussi des dispositifs à béquille débrayée : lorsque l'accès depuis l'extérieur est condamné, un mécanisme de débrayage découple la rotation de la béquille de la rotation du fouillot. Une butée limite le mouvement de la béquille, et un ressort de torsion rappelle celle-ci vers sa position d'attente qui est généralement horizontale.Also known devices with disengaged jack: when access from outside is condemned, a disengagement mechanism decouples the rotation of the crutch of the rotation of the follower. A stop limits the movement of the stand, and a torsion spring recalls it to its standby position which is generally horizontal.

Ces deux solutions ont en commun l'inconvénient de permettre que la porte puisse être vandalisée par un appui soutenu sur la béquille, que celle-ci soit bloquée en position d'attente horizontale ou bloquée en fin de course contre une butée. Le dispositif est endommagé soit parce que la béquille plie ou se rompt, soit parce que l'intérieur de l'organe de manoeuvre se déforme ou se rompt.These two solutions have in common the disadvantage of allowing the door can be vandalized by a sustained support on the stand, that it is locked in horizontal waiting position or blocked at the end of stroke against a stop. The device is damaged either because the stand creases or breaks, or because the inside of the operating member is deformed or breaks.

Le document GB 2325020 décrit un organe de manoeuvre selon le préambule de la revendication 1.The document GB 2325020 discloses an actuator according to the preamble of claim 1.

L'invention a pour objet de remédier à ce problème, et de fournir un organe de manoeuvre alternatif de type demi-ensemble qui ne soit pas détérioré par un trop grand effort sur la béquille. De préférence la solution selon l'invention doit présenter une bonne robustesse pour un encombrement minimal.The object of the invention is to remedy this problem, and to provide an alternating actuator of the half-assembly type which is not damaged by too much effort on the stand. Preferably the solution according to the invention must have good robustness for a minimum space requirement.

A cet effet, l'invention propose un organe de manoeuvre adapté à être monté sur un vantail comportant une serrure par une face définissant un plan de référence perpendiculaire à une direction axiale, ledit organe de manoeuvre comportant un corps contenant au moins en partie :

  • un support de béquille en rotation autour d'un premier axe parallèle à ladite direction axiale et fixe par rapport audit corps, ledit support de béquille comportant une portion de butée déportée radialement par rapport audit premier axe,
  • un fouillot en rotation autour d'un second axe parallèle à ladite direction axiale et fixe par rapport audit corps, adapté à agir sur un carré de la serrure,
  • un cylindre de commande accessible depuis l'extérieur du corps, présentant au moins deux positions et adapté à être basculé de l'une à l'autre en réponse à l'action d'un utilisateur,
  • un ensemble mobile de transmission mobile en translation suivant une direction de translation parallèle au plan de référence, commutable entre au moins une configuration embrayée et une configuration débrayée sous l'action dudit cylindre de commande et tel que la rotation du support de béquille entraîne la translation dudit ensemble mobile de transmission, et que dans la configuration embrayée la translation dudit ensemble mobile de transmission entraîne la rotation du fouillot caractérisé en ce que
  • le corps contient de plus un système de butée porté par ledit corps, déformable réversiblement entre au moins deux conformations et adapté dans une première conformation à coopérer avec ladite portion de butée pour définir une position angulaire de butée pour le support de béquille obtenue par rotation par rapport à une position de repos dans laquelle la portion de butée n'est pas en contact avec le système de butée ; ledit système de butée se déformant pour des efforts croissants exercés sur le support de béquille jusqu'à une deuxième conformation pour laquelle la portion de butée échappe audit système de butée par glissement au contact du celui-ci, ledit système de butée étant rappelé élastiquement vers sa première conformation.
For this purpose, the invention proposes an operating member adapted to be mounted on a leaf comprising a lock by a face defining a reference plane perpendicular to an axial direction, said actuating member comprising a body containing at least partly:
  • a stand support rotating about a first axis parallel to said axial direction and fixed relative to said body, said stand support having a stop portion radially offset relative to said first axis,
  • a follower rotating about a second axis parallel to said axial direction and fixed relative to said body, adapted to act on a square of the lock,
  • a control cylinder accessible from outside the body, having at least two positions and adapted to be toggled from one to the other in response to the action of a user,
  • a movable transmission assembly movable in translation in a direction of translation parallel to the reference plane, switchable between at least one engaged configuration and a disengaged configuration under the action of said control cylinder and such that the rotation of the stand support causes the translation of said mobile transmission unit, and that in the engaged configuration the translation of said mobile transmission unit causes the rotation of the follower characterized in that
  • the body further contains a stop system carried by said body, deformable reversibly between at least two conformations and adapted in a first conformation to cooperate with said abutment portion to define an angular position of abutment for the stand support obtained by rotation by relative to a rest position in which the abutment portion is not in contact with the abutment system; said abutment system deforming for increasing efforts exerted on the stand support to a second conformation for which the abutment portion escapes said abutment system by sliding in contact therewith, said abutment system being resiliently biased towards his first conformation.

Ce dispositif présente l'avantage de ne pas pouvoir être endommagé par une action en rotation trop importante sur la béquille, c'est-à-dire d'être protégé contre le vandalisme. En effet, l'ensemble mobile de transmission permet de débrayer la rotation du fouillot de la rotation du support de béquille, et quand un effort en rotation trop élevé est appliqué, le système de butée se déforme réversiblement et laisse tourner ledit support de béquille, ce qui permet d'éviter la rupture ou l'endomagement du dispositif. Par ailleurs, l'ensemble mobile en translation étant mobile suivant une direction parallèle au plan de référence, l'encombrement dans la direction axiale est limité.This device has the advantage of not being able to be damaged by too much rotation action on the stand, that is to say to be protected against vandalism. Indeed, the mobile transmission unit allows to disengage the rotation of the follower of the rotation of the stand support, and when a too high rotational force is applied, the stop system reversibly deforms and allows said stand support to rotate, thereby avoiding breaking or the damage of the device. Furthermore, the movable assembly in translation being movable in a direction parallel to the reference plane, the space in the axial direction is limited.

Préférentiellement, l'ensemble mobile de transmission comprend un premier élément de transmission coopérant avec le support de béquille, et un deuxième élément de transmission coopérant dans la configuration embrayée avec le fouillot, ledit deuxième élément de transmission subissant, entre la configuration débrayée et la configuration embrayée, par rapport audit premier élément de transmission, un décalage transversal à ladite direction de translation.Preferably, the mobile transmission unit comprises a first transmission element cooperating with the stand support, and a second transmission element cooperating in the engaged configuration with the follower, said second transmission element undergoing, between the disengaged configuration and the configuration. engaged, with respect to said first transmission element, an offset transverse to said translation direction.

Préférentiellement, l'ensemble mobile de transmission est composé d'une plaquette montée en translation par rapport au corps et d'une pièce d'embrayage montée en rotation par rapport à ladite plaquette, le premier élément de transmission étant porté par ladite plaquette, et le deuxième élément de transmission étant porté par ladite pièce d'embrayage. Ces caractéristiques offrent l'avantage de la simplicité et de la solidité, pour un encombrement limité.

En référence à la figure 1, un organe de manoeuvre 1 dit demi-ensemble destiné à être fixé sur une porte par une face 2 parallèle à un plan de référence comprend un corps 3 allongé, un support de béquille 4 en rotation autour d'un premier axe perpendiculaire au plan de référence, un fouillot 5 en rotation autour d'un deuxième axe ici confondu avec le premier axe, un cylindre de commande 6, un élément mobile de transmission 7 monté en translation par rapport au corps 3, des lamelles élastiques 8 formant un système de butée, un ressort 9 et une pièce de condamnation 10. La position de repos de la béquille est perpendiculaire à la direction d'allongement du corps 3 et parallèle au plan de référence.With reference to the figure 1 , an operating member 1 said half-assembly intended to be fixed on a door by a face 2 parallel to a reference plane comprises an elongated body 3, a stand support 4 rotated about a first axis perpendicular to the plane of reference, a follower 5 in rotation about a second axis here confused with the first axis, a control cylinder 6, a movable transmission member 7 mounted in translation relative to the body 3, elastic strips 8 forming a stop system , a spring 9 and a locking piece 10. The rest position of the stand is perpendicular to the direction of elongation of the body 3 and parallel to the reference plane.

Les figures 2, 3 et 4 montrent de manière plus détaillée le support de béquille 4, qui comporte plusieurs sections décalées selon son axe, parmi lesquelles une section d'action 41 et une section de butée 42. Les deux sections 41 et 42 sont allongées radialement, de telle sorte que leur circonférence n'est pas un cercle de centre porté par l'axe du support de béquille, mais en diffère par la présence de renflements périphériques.The Figures 2, 3 and 4 show in more detail the stand support 4, which comprises a plurality of axially offset sections, among which an action section 41 and a stop section 42. The two sections 41 and 42 are elongate radially, so that their circumference is not a center circle carried by the axis of the stand support, but differs by the presence of peripheral bulges.

La section d'action 41 a une forme générale de noeud papillon incluant une portion cylindrique centrale reliée par deux portions rétrécies à deux portions d'action 410 ayant la forme de protubérances périphériques.The action section 41 has a general bow-tie shape including a central cylindrical portion connected by two narrowed portions to two action portions 410 having the shape of peripheral protuberances.

La section de butée 42 a une forme générale ovale et ses parties excentrées forment deux portions de butée 420.The abutment section 42 has a generally oval shape and its eccentric portions form two abutment portions 420.

Enfin le support de béquille 4 comporte une section de fixation de la béquille 43 de type classique, connue de l'homme du métier. Par ailleurs, le support de béquille 4 possède un plan de symétrie qui inclut son axe.Finally the stand support 4 comprises a fixing section of the stand 43 of conventional type, known to those skilled in the art. Furthermore, the stand support 4 has a plane of symmetry which includes its axis.

La figure 5 représente le fouillot 5 de l'organe de manoeuvre, qui comporte un axe de rotation, deux zones d'appui 51 déportées par rapport à cet axe, un évidement 52 adjacent à chacune des zones d'appui 51, ainsi qu'une prise 53 adaptée à agir sur le carré de la serrure (visible en figure 7, non représenté sur les autres figures), de manière classique connue de l'homme du métier. Les zones d'appui 51 sont incurvées et convexes de telle sorte qu'un effort peut y être exercé sous différents angles. Elles sont symétriques l'une de l'autre par rapport à un plan incluant l'axe de rotation du fouillot 5. L'évidement 52 est symétrique de lui-même par rapport à ce même plan.The figure 5 represents the nut 5 of the operating member, which comprises an axis of rotation, two bearing zones 51 offset relative to this axis, a recess 52 adjacent to each of the bearing zones 51, and a socket 53 adapted to act on the square of the lock (visible in figure 7 , not shown in the other figures), in a manner conventionally known to those skilled in the art. The bearing areas 51 are curved and convex so that a force can be exerted from different angles. They are symmetrical to one another with respect to a plane including the axis of rotation of the follower 5. The recess 52 is symmetrical about itself with respect to this same plane.

En référence à la figure 6, l'ensemble mobile en translation 7 comporte une plaquette 71 et une pièce de débrayage 72 mobile en rotation par rapport à la plaquette 71 via une liaison pivot réalisable classiquement par l'homme du métier.With reference to the figure 6 , the movable assembly in translation 7 comprises a plate 71 and a disengaging member 72 movable in rotation relative to the plate 71 via a pivot connection classically feasible by the skilled person.

La plaquette 71 est plane, de forme générale rectangulaire et admet un plan de symétrie perpendiculaire à son plan et parallèle à son plus grand côté. La liaison pivot reliant la plaquette 71 et la pièce de débrayage 72 est positionnée sur la plaquette 71 près d'un des petits côtés du rectangle. La plaquette comporte une ouverture centrale selon une directrice perpendiculaire au plan de la plaquette, le contour de cette ouverture étant ici fermé. La tranche de l'ouverture centrale de la plaquette 71 du côté de la liaison pivot comporte successivement une première portion plane, une portion circulaire et une deuxième portion plane, formant une surface d'appui 73 dirigée à l'opposé de la liaison pivot.The wafer 71 is flat, of generally rectangular shape and has a plane of symmetry perpendicular to its plane and parallel to its longer side. The pivot connection connecting the plate 71 and the clutch part 72 is positioned on the plate 71 near one of the short sides of the rectangle. The wafer has a central opening in a direction perpendicular to the plane of the wafer, the contour of this opening being here closed. The edge of the central opening of the wafer 71 on the pivot connection side comprises successively a first flat portion, a circular portion and a second flat portion, forming a bearing surface 73 directed away from the pivot connection.

La pièce de débrayage 72 est plane, de forme générale allongée et admet un plan de symétrie perpendiculaire à son plan et parallèle à sa direction longitudinale. La liaison pivot reliant la plaquette 71 et la pièce de débrayage 72 est positionnée sur la pièce de débrayage 72 en une localisation excentrée sur la direction longitudinale. La pièce de débrayage 72 comporte une ouverture centrale selon une directrice perpendiculaire à son plan, le contour de cette ouverture étant ici fermé. Deux ergots 75 formant des dents sont saillants vers l'intérieur de l'ouverture centrale de la pièce de débrayage 72. La tranche de l'ouverture centrale présente, au niveau de chaque ergot 75, une surface d'action 74 dirigée dans la direction de la liaison pivot, une partie de la surface d'action 74 étant concave. Les ergots 75 et les surfaces d'action 74 sont déportés par rapport à la liaison pivot.The disengagement piece 72 is flat, generally elongated and has a plane of symmetry perpendicular to its plane and parallel to its longitudinal direction. The pivot connection connecting the plate 71 and the clutch part 72 is positioned on the clutch part 72 in an eccentric location on the longitudinal direction. The disengagement piece 72 has a central opening in a direction perpendicular to its plane, the contour of this opening being closed here. Two lugs 75 forming teeth protrude inwardly of the central opening of the release member 72. The edge of the central opening has, at each lug 75, an action surface 74 directed in the direction of the pivot connection, a part of the action surface 74 being concave. The lugs 75 and the action surfaces 74 are offset relative to the pivot connection.

En référence à la figure 7, la béquille de l'organe de manoeuvre présente une position de repos ou de rappel classique, typiquement horizontale quand l'organe de manoeuvre est posé sur une porte, et perpendiculaire à la grande dimension du corps 3.With reference to the figure 7 , the stand of the operating member has a conventional rest or return position, typically horizontal when the operating member is placed on a door, and perpendicular to the large dimension of the body 3.

Comme il apparaît aux figures 7, 8, 9 et 10, la plaquette 71 est, en fonctionnement, mobile par rapport au corps 3 en translation selon une direction de translation parallèle au plan de référence et perpendiculaire à la position de repos de la béquille. La pièce d'embrayage 72 est mobile en rotation par rapport à la plaquette 71 autour d'un axe perpendiculaire au plan de référence. La grande dimension de la plaquette 71 est positionnée perpendiculairement à la position de repos de la béquille et la liaison pivot reliant la plaquette 71 à la pièce d'embrayage 72 est positionnée vers le haut.As it appears from Figures 7, 8 , 9 and 10 , the plate 71 is, in operation, movable relative to the body 3 in translation along a direction of translation parallel to the reference plane and perpendicular to the rest position of the stand. The clutch part 72 is rotatable relative to the plate 71 about an axis perpendicular to the reference plane. The large dimension of the plate 71 is positioned perpendicular to the rest position of the stand and the pivot connection connecting the plate 71 to the clutch part 72 is positioned upwards.

En référence à la figure 7, la pièce de condamnation 10 est, par rapport au corps 3, mobile en translation parallèlement au plan de référence et parallèlement à la direction de la béquille dans sa position de repos. La pièce de condamnation 10 est, par rapport au corps 3, également mobile en rotation autour d'un axe perpendiculaire au plan de référence. Cette liaison est réalisée par un ergot cylindrique porté par le corps 3 ou solidaire de celui-ci et coulissant dans une fente oblongue pratiquée à travers la pièce de condamnation 10, perpendiculairement au plan de référence. Cette fente est allongée parallèlement à la direction de la béquille dans sa position de repos et borgne en ses deux bouts.With reference to the figure 7 , the locking piece 10 is, relative to the body 3, movable in translation parallel to the reference plane and parallel to the direction of the stand in its rest position. The locking piece 10 is, relative to the body 3, also rotatable about an axis perpendicular to the reference plane. This connection is achieved by a cylindrical lug carried by the body 3 or integral thereof and sliding in an oblong slot made through the locking member 10, perpendicular to the reference plane. This slot is elongated parallel to the direction of the stand in its rest position and one-eyed at both ends.

La pièce de condamnation 10 est également, par rapport à la pièce d'embrayage 72, mobile en translation parallèlement au plan de référence et mobile en rotation autour d'un axe perpendiculaire au plan de référence. Cette liaison est réalisée par un ergot cylindrique porté par la pièce d'embrayage 72 et coulissant dans une fente oblongue pratiquée à travers la pièce de condamnation 10 perpendiculairement au plan de référence. Cette fente est allongée perpendiculairement à la direction de la béquille dans sa position de repos et borgne en ses deux bouts.The locking piece 10 is also, relative to the clutch part 72, movable in translation parallel to the reference plane and mobile in rotation about an axis perpendicular to the reference plane. This connection is made by a cylindrical lug carried by the clutch part 72 and sliding in an oblong slot made through the locking part 10 perpendicularly to the reference plane. This slot is elongated perpendicular to the direction of the stand in its rest position and blind at both ends.

La rotation du cylindre de commande 6 commande de manière classique, connue de l'homme du métier, le déplacement de la pièce de condamnation 10, qui entraîne la rotation de la pièce d'embrayage 72 par rapport à la plaquette 71, l'amenant de la configuration débrayée (figures 7 et 8) à la configuration embrayée (figures 9 et 10). Cette rotation entraîne un décalage transversal à la direction de translation de l'ensemble mobile de translation 7 d'un ergot 75 et de la surface d'action 74 correspondante.The rotation of the control cylinder 6 controls in a conventional manner, known to those skilled in the art, the displacement of the locking piece 10, which causes the clutch part 72 to rotate with respect to the plate 71, causing it to rotate. the disengaged configuration ( Figures 7 and 8 ) to the engaged configuration ( Figures 9 and 10 ). This rotation causes a shift transverse to the direction of translation of the mobile translation assembly 7 of a lug 75 and the corresponding action surface 74.

Le ressort 9 en appui contre le corps 3 maintient la plaquette 71 contre le support de béquille 4, par une action contre la tranche extérieure supérieure de la plaquette 71, qui est la plus proche de la liaison pivot. Une portion d'action 410 en contact avec une portion plane de la surface d'appui 73.The spring 9 bearing against the body 3 holds the plate 71 against the stand support 4, by an action against the upper outer edge of the wafer 71, which is closest to the pivot connection. An action portion 410 in contact with a flat portion of the bearing surface 73.

En configuration débrayée (figures 7 et 8) ou embrayé (figures 9 et 10), une action sur la béquille provoque la rotation du support de béquille 4, dont une portion d'action 410 pousse la surface d'appui 73 vers le haut, ce qui entraîne la translation de l'ensemble mobile de transmission 7 selon sa direction de translation, à l'encontre du ressort 9. La circonférence de la section d'action 41 glisse sur la surface d'appui 73. Ces mouvements sont réversibles.In disengaged configuration ( Figures 7 and 8 ) or engaged ( Figures 9 and 10 ), an action on the stand causes the rotation of the stand support 4, an action portion 410 pushes the bearing surface 73 upwards, which causes the translation of the mobile transmission assembly 7 in its direction translationally, against the spring 9. The circumference of the action section 41 slides on the bearing surface 73. These movements are reversible.

Il ressort de la figure 8, que l'enveloppe de la circonférence de la section d'action (41) comprend une zone à une première distance de l'axe du support de béquille (4) et une deuxième zone à une deuxième distance de cet axe, la deuxième distance étant supérieure à la première distance. L'enveloppe de la circonférence de la section d'action (41) glisse au contact de la surface d'appui 73.It appears from figure 8 that the circumference of the circumference of the action section (41) comprises an area at a first distance from the axis of the stand support (4) and a second area at a second distance from this axis, the second distance being greater than the first distance. The envelope of the circumference of the action section (41) slides in contact with the bearing surface 73.

En configuration débrayée (figures 7 et 8), les ergots 75 n'interagissent pas avec le fouillot 5, et les surfaces d'action 74 ne sont alors pas en contact avec les zones d'appui 51. Aucune action sur le carré de la serrure ne résulte de l'action sur la béquille.In disengaged configuration ( Figures 7 and 8 ), the lugs 75 do not interact with the follower 5, and the action surfaces 74 are then not not in contact with the bearing areas 51. No action on the square of the lock is the result of the action on the stand.

En configuration embrayée (figures 9 et 10), un ergot 75 est positionné en regard d'une zone d'appui 51 du fouillot 5. Une action sur la béquille provoque comme précédemment la rotation du support de béquille 4, qui entraîne, par l'intermédiaire d'une portion d'action 410 en contact avec une portion plane de la surface d'appui 73 la translation de l'ensemble mobile de transmission 7 selon sa direction de translation. Une surface d'action 74 entre en contact avec une zone d'appui 51 et la surface d'action 74 pousse la zone d'appui 51. L'ergot 75 correspondant s'engage dans l'évidement 52, la poussée de la zone d'appui 74 sur la surface d'action 51 provoque la rotation du fouillot autour de son axe, la surface d'action 74 roule sur la zone d'appui 51 et l'insertion de l'ergot 75 dans l'évidement 52 permet de prolonger l'action de la surface d'action 74 sur la zone d'appui 51. La translation de l'ensemble mobile de transmission 7 provoque par ce mécanisme la rotation du fouillot 5 autour de son axe. Ces mouvements sont réversibles.In engaged configuration ( Figures 9 and 10 ), a lug 75 is positioned opposite a bearing zone 51 of the follower 5. An action on the stand causes as before the rotation of the stand support 4, which leads, via a portion of action 410 in contact with a flat portion of the bearing surface 73 the translation of the mobile transmission unit 7 in its translation direction. An action surface 74 comes into contact with a bearing zone 51 and the action surface 74 pushes the bearing zone 51. The corresponding pin 75 engages in the recess 52, the thrust of the zone support 74 on the action surface 51 causes the rotation of the follower about its axis, the action surface 74 rolls on the bearing zone 51 and the insertion of the pin 75 in the recess 52 allows to extend the action of the action surface 74 on the support zone 51. The translation of the mobile transmission unit 7 causes this mechanism to rotate the follower 5 about its axis. These movements are reversible.

Quand l'action sur la béquille se termine, le ressort 9 rappelle l'élément mobile de transmission 7 et le support de béquille 4 vers leur position de repos ou de rappel (voir figures 7 et 9).When the action on the stand comes to an end, the spring 9 recalls the mobile transmission element 7 and the stand support 4 towards their resting or restoring position (see FIG. figures 7 and 9 ).

Les figures 11, 12, 13 et 14 représentent une vue de coupe de la section de butée 42 et des portions de butée 420 du support de béquille 4 et du système de butée de l'organe de manoeuvre en quatre dispositions.The Figures 11, 12, 13 and 14 are a sectional view of the abutment section 42 and stop portions 420 of the stand support 4 and the stop system of the actuator in four arrangements.

Tout d'abord, la figure 11 montre la position du mécanisme en position initiale où la béquille est en position de repos, classiquement horizontale (voir figures 7 et 9). La section de butée 42 n'est pas au contact des lamelles élastiques 8 qui sont portées par le corps 3.First, the figure 11 shows the position of the mechanism in the initial position where the stand is in the position of rest, classically horizontal (see figures 7 and 9 ). The abutment section 42 is not in contact with the elastic lamellae 8 which are carried by the body 3.

La figure 12 montre la position du mécanisme après une rotation de la béquille de 45° ou d'environ 45° par rapport à la position initiale (voir figures 8 et 10). La section de butée 42 est via ses portions de butée 420 en contact avec les lamelles élastiques 8, en sorte que la résistance provoquée par ce contact peut permettre à l'opérateur actionnant la béquille de ressentir que le mécanisme est en butée. On comprend que cette résistance est opposée par les lamelles élastiques, qui constituent le système de butée, car celles-ci sont portées par le corps 3 en sorte de provoquer cette résistance (figure 1).The figure 12 shows the position of the mechanism after a rotation of the stand of 45 ° or about 45 ° with respect to the initial position (see figures 8 and 10 ). The abutment section 42 is via its stop portions 420 in contact with the elastic lamellae 8, so that the resistance caused by this contact can allow the operator operating the stand to feel that the mechanism is in abutment. We understand that this resistance is opposed by the elastic strips, which constitute the stop system, because these are carried by the body 3 so as to cause this resistance ( figure 1 ).

La figure 13 montre la position du mécanisme après une rotation supplémentaire de la béquille. Les lamelles élastiques 8 se sont déformées vers une conformation de déformation pour laisser de l'espace aux portions de butée 420, qui glissent au contact des lamelles élastiques 8, du fait de l'effort appliqué au support de béquille 4 et de son cumul. On comprend que la déformation des lamelles élastiques 8 est causée par l'action conjuguée de cet effort qui est transmis par le support de béquille aux lamelles et de la résistance opposée aux lamelles élastiques 8 par le corps 3 qui les porte. De manière importante, la déformation des lamelles élastiques 8 se fait sans dépasser la limite élastique du matériau choisi, ici de l'acier à ressort. Le choix de ce matériau et des caractéristiques géométriques des lamelles 8 est facilement réalisé par l'homme du métier.The figure 13 shows the position of the mechanism after additional rotation of the stand. The elastic strips 8 have deformed towards a deformation conformation to leave space for the abutment portions 420, which slide in contact with the elastic strips 8, because of the force applied to the stand support 4 and its accumulation. It is understood that the deformation of the elastic lamellae 8 is caused by the combined action of this force which is transmitted by the stand support to the lamellae and the resistance opposed to the elastic lamellae 8 by the body 3 which carries them. Importantly, the deformation of the elastic strips 8 is without exceeding the elastic limit of the material chosen, here spring steel. The choice of this material and the geometric characteristics of the slats 8 is easily achieved by those skilled in the art.

La figure 14 montre la position du mécanisme après une nouvelle rotation supplémentaire de la béquille. Les portions de butée 420 se sont écartées des lamelles 8 qui sont revenues dans leur conformation initiale, du fait de l'effort appliqué au support de béquille 4 et de son cumul. La béquille est en position inversée (non représenté) par rapport à sa position d'origine.The figure 14 shows the position of the mechanism after a further rotation of the stand. The abutment portions 420 have moved away from the slats 8 which have returned to their initial conformation, due to the force applied to the support crutch 4 and its accumulation. The stand is in the inverted position (not shown) relative to its original position.

Un demi-tour supplémentaire, dans un sens ou dans l'autre, est nécessaire pour ramener l'organe de manoeuvre à sa position initiale représentée en figure 11.An additional half-turn, in one direction or the other, is necessary to return the operating member to its initial position shown in FIG. figure 11 .

Il ressort des figures 11 à 14 ainsi que de la figure 1 que le système de butée agit dans une première conformation en sorte d'empêcher une rotation complète dudit support de béquille 4, et est adapté dans une conformation déformée à laisser tourner le support de béquille 4 de sorte que dans la configuration débrayée de l'ensemble mobile de translation une rotation complète dudit support de béquille 4 est possible, et on comprend que les extrémités des lamelles élastiques 8, portées par le corps 3, sont dans la même position dans les deux conformations. La déformation du système de butée de sa première conformation vers sa conformation déformée se produit pour un effort en rotation appliqué au support de béquille anormalement soutenu ou élevé, typique d'une situation dite de vandalisme.It emerges Figures 11 to 14 as well as figure 1 that the abutment system acts in a first conformation so as to prevent a complete rotation of said stand support 4, and is adapted in a deformed conformation to let the stand support 4 rotate so that in the disengaged configuration of the assembly mobile translation of a complete rotation of said stand support 4 is possible, and it is understood that the ends of the elastic strips 8, carried by the body 3, are in the same position in both conformations. The deformation of the abutment system from its first conformation to its deformed conformation occurs for a rotational force applied to the stand support abnormally sustained or high, typical of a situation called vandalism.

Par ailleurs, en référence aux figures 6 et 8 la surface d'appui 73 de l'ensemble mobile de transmission 7 comporte une partie plane et une partie circulaire de telle sorte que la rotation du support de béquille 4 provoque la translation de l'ensemble mobile de transmission 7 quand une portion d'action 410 est au contact d'une partie plane de la surface d'appui 73, et que, à l'inverse, la rotation du support de béquille 4 ne provoque pas la translation de l'ensemble mobile de transmission 7 quand la portion d'action 410 est au contact de la partie circulaire, configuration qui correspond aux conformations de déformation du système de butée (figure 13).Moreover, with reference to figures 6 and 8 the bearing surface 73 of the mobile transmission unit 7 comprises a flat part and a circular part such that the rotation of the stand support 4 causes the translation of the mobile transmission assembly 7 when a portion of action 410 is in contact with a flat portion of the bearing surface 73, and that, conversely, the rotation of the stand support 4 does not cause the translation of the mobile transmission assembly 7 when the portion of action 410 is in contact with the circular part, which configuration corresponds to the conformations of deformation of the stop system ( figure 13 ).

Enfin, la position du fouillot quand le support de béquille est en butée (figure 12) est telle que le carré de la serrure est en position adaptée à l'ouverture de la porte.Finally, the position of the follower when the stand support is in abutment ( figure 12 ) is such that the square of the lock is in a position adapted to the opening of the door.

L'invention ne saurait être limitée aux exemples de réalisation décrits ci-dessus.The invention can not be limited to the embodiments described above.

On peut notamment envisager, en restant dans le cadre de la présente invention, une variante où la pièce de débrayage peut être montée en translation par rapport à la plaquette dans une direction transversale à la direction de translation de celle-ci par rapport au corps.It is possible to envisage, within the scope of the present invention, a variant in which the disengaging part can be mounted in translation relative to the wafer in a direction transverse to the direction of translation thereof relative to the body.

On peut également envisager, par exemple, que la conversion du mouvement de rotation du support de béquille en un mouvement de translation de l'élément mobile de transmission se fasse par un système de crémaillère.It can also be envisaged, for example, that the conversion of the rotational movement of the stand support into a translation movement of the movable transmission element is done by a rack system.

On peut également envisager que la conversion du mouvement de translation de l'élément mobile de transmission en un mouvement de rotation du fouillot se fasse également par un système de crémaillère.It can also be envisaged that the conversion of the translational movement of the mobile transmission element into a rotation movement of the follower is also done by a rack system.

Le système de butée peut éventuellement, en restant également dans le cadre de la présente invention, comporter à la place de lamelles flexibles par exemple un système de lamelles non flexibles retenues par des ressorts de compression.The abutment system may optionally, while also remaining within the scope of the present invention, comprise instead flexible slats for example a system of non-flexible slats retained by compression springs.
